Experiences from the action plan concerning noise abatement measures developed in the city of Modena are described. The paper shows noise levels measured after traffic calming measures, after the construction of a noise barrier and a roundabout and after the laying of low-noise pavements. A method for the new action plan design is tested on a large urban area based on a noise map and on a priority index for noise reduction actions taking into account the noise exposure levels and the number of exposed people.
